Over the bus, use the appropriate SCPI commands to determine the measurement range and
the compliance setting. Once those parameters are known, compare them as previously
explained to determine the compliance in effect.
When sourcing current, use the following commands to acquire the measurement range and
the compliance setting:
VOLTage:RANGe?
VOLTage:PROTection?
When sourcing voltage, use the following commands to acquire the measurement range and
the compliance setting:
CURRent:RANGe?
CURRent:PROTection?

Overheating protection

Proper ventilation is required to keep the SourceMeter from overheating. See the
"CAUTION" located at the beginning of Section 3 for details on maintaining proper
ventilation.
The SourceMeter has an over-temperature protection circuit that will turn the output off in
the event that the instrument overheats. If the output trips due to overheating, a message indi-
cating this condition will be displayed. You will not be able to turn the output back on until the
instrument cools down.
